Off topic but I can't believe you hate subaru. He is by far one of the best written characters OAT and both MCs weakness comes from the fact they are ACTUALLY weak. They rely on others because they know if they grow a "backbone" they will most likely end up hindering those who really are strong.

It's just a personal thought then again I'm not also looking for an alpha MC cause yeah no one likes an overpowered hero or so. I get the part of taking advantage on ur allies powers it's not that bad I mean fate/stay night somewhat has it and it's not that bad.
My personal point on Subaru tho is that he has too much selfish ego and tries to think very irrational. Idc if he gets himself killed I mean the guy never dies in time rule way, but his mistakes doesn't improve him which leads to sometimes getting the others in danger.
This is just my personal thoughts but I still hate the part of him asking rem to just runaway with him even already knowing his inlove with Emillia. It's really scummy, I don't mind if he gets a harem, but don't treat them like that like jeez.
Also the part you said having a backbone and hindering the strong. It doesn't really matter much whether ur Op or lame what matters is that u don't act selfishly and not be a burden. I can't explain it much but it's just like Kazuma in Konosuba in a sense. The guy is weak af but he still does things in a safe and rational way and also using the advantages of his teammates.
